Run LU a couple of times to make sure that you have SP1 and some follow-up fixes. After that, push out the remote agent to the Domino server and re-boot the server. Even if you are on the latest updates, push out the remote agent agent again to the Domino server and re-boot the server.

As an additional trouble-shooting step, make the BE remote agent service start manually and then start this service after the Domino service has started.
